Thanks Michael. It wasn't actually pine needles - though it looks like that. It was dry grass. There were no pines nearby. I can now see that the GPS on my phone must be stuffed. Rather than being near Yarralumla it was in Black Mtn Reserve. I have fixed the position now.
@PaulDoy @MichaelMulvaney in that case, and looking at the pileus of your specimen, I suggest this is either a Tylopilus sp or one of the many undescribed native boletes.
